Recently, the new residential project “Heguang Yu Lake Mansion” developed by the central enterprise Poly Group of the Chinese Communist Party in Zhengzhou, Henan, has been collectively complained by homeowners. The luxury houses, which were purchased for over 1 million yuan, started to develop extensive mold under the floor after two years of occupancy. This has led to residents feeling unwell, and even some children have contracted pneumonia. However, after homeowners reported the situation to the property management, the issue has yet to be resolved. Currently, many homeowners can only stay in hotels or rent houses, facing the dilemma of not being able to return to their own homes.
According to a report by Tencent News on February 10, a homeowners’ representative in the community revealed that many affected neighbors in the area live in million-dollar “luxury houses.” Starting from October 2025, residents have been complaining about an unremovable musty smell in their homes, but initially, not much attention was paid to it.
It wasn’t until a child from one homeowner’s family was hospitalized for a lung infection related to mold that everyone became alert. In order to find the source, some neighbors dismantled the wooden floor in their bedrooms, only to discover widespread black mold underneath. The news quickly spread among homeowners, prompting more and more neighbors to conduct their own inspections.
According to the homeowner, there are over 1,400 households in the community, with an occupancy rate of about fifty percent. Through self-inspection, it was found that the mold issue was extremely serious. After opening the top layer of wooden flooring in the bedroom, black mold patches were revealed underneath. However, this was not the bottom layer; between the wooden floor and the cement ground, there is another layer of boards (“groove boards”). Upon opening this layer, the smell and mold growth were even worse. Some residents found no mold spots when opening the first layer of wood, but only discovered mold growth when removing the layer beneath.
The homeowner expressed that the smell is extremely foul, causing discomfort for some older neighbors who felt unwell for several days after entering the homes, experiencing dizziness, coughing, and respiratory discomfort. Some homeowners even found insects in their homes.
Subsequently, maintenance personnel from the property service center, “Zhengzhou Zhanli Real Estate Co., Ltd.,” conducted inspections on over 600 households, determining only over 200 households as having “severe mold” (meaning mold covering more than one-third of the area). The homeowner mentioned, “For homes like ours with a strong mold smell and children already affected health-wise, unless the mold area after dismantling the floor is ‘large enough,’ it’s not within their ‘scope of handling.'”
Some homeowners investigated building drawings in archives and found discrepancies between the actual construction and the drawings. According to the drawings, the middle layer of boards should have been filled with cement, but it was constructed with other materials. Homeowners suspect cut corners and inferior materials were used in the construction.
In response, Zhengzhou Zhanli Real Estate Co., Ltd. claimed that condensation occurred due to this being the first year of heating, leading to moisture accumulating in the gap of the “groove boards,” causing mold growth. However, homeowners refuted this explanation, pointing out that many homeowners had not even turned on the heating, and some had never lived in the houses after receiving them but still experienced mold issues.
The homeowner lamented that from the discovery of the problem in October last year until now, several months have passed. Many neighbors are afraid to return home and can only take their families to live in hotels or rent houses, enduring double economic pressure. The house they bought with their life savings has now become a shadow over their hearts and a threat to their health.
Public records show that China Poly Group Co., Ltd. is a large central state-owned enterprise supervised by the State-owned Assets Supervision and Administration Commission of the State Council of the Chinese Communist Party. It has 11 main subsidiaries engaged primarily in military equipment import and export, real estate, culture and art, as well as mining resource investment and development.
Netizens have criticized, “Unscrupulous developers, unethical central enterprises.” “Cutting corners in construction, not following drawings, supervision seems non-existent, victims have nowhere to complain, how is this different from manslaughter?” “This is the reality, a mess! Nowhere to lodge complaints.” “If this happened in the United States, Poly would be bankrupted.”
